SPECFICATION forming part of Letters Patent No. 359,947,6.ated March 22,1887.

Application led October-25,1884. Serial No. 146,690. (No model.)

To all whom it may concern:

Be it known that I. CHARLES HENREY WIL- SON, a citizen of the UnitedStates, residing at Paducah, in the county of McCracken and State ofKentucky, have invented a new and useful Improvement in Locomotives, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to an improvement in locomotives; and it consistsin the peculiar construction and combination of devices, that will bemore fully set forth hereinafter, and particularly pointed out in theclaims.

In the accompanying drawings, Figure l is partly a side elevation andpartly a vertical central longitudinal sectional view of a locomotivewith my improved devices attached thereto. Fig. 2 is a verticalsectional view of the same, taken on the line a; of Fig. l. Fig. 3 is adetailed view.

This improvement relates more particularly to locomotiveengines;` but itmay be appliedto steam-boiler or other furnaces.

The object of the invention is to provide improved devices for arrestingthe sparks and to do away with the annoyance of smoke, soot, dust, 85e.,and to increase the draft and de crease the consumption of fuel.

Referring by letter to the drawings, A designates the boiler ofthelocomotive, which is provided with the fire-box or furnace B, the grateC, the ash-pit D, ilues E, smoke-box F, and stack G, in the usualmanner. In the smoke-box, directly facing the head of the boiler, is ahood, H, which forms an elbow or rearwardly-extending horizontal portionof a spark-funnel, l,whichis secured vertically in the smoke-box andextends downwardly below the lower side thereof for a suitable distance.The bottoni of the spark-funnel is formed by the pivoted balanced valveK, to the protruding ends of the shaft of which are secured levers L,that are weighted at theirlower ends, so as to keep the valve K normallyin a horizontal position, closing the lower end of the sparkfunnel. Acord or rod, lll, is secured to the upper end of one of the levers L,and extends therefrom to the eab of the locomotive in easy reach of theengineer.

N represents pipes th at extend from the ashpit and enter the hood H,and have their ends turned downwardly therein, and O represents pipesthat are connected to the steam-chests of the engines and conduct theexhaust-steam therefrom into the hood, as shown, the arrows which arenot feathercdindicating the currents of exhaust-steam in the drawings.

l? represents a sleeve, which is placed on the end of the hood and isadapted to slide back and forth thereon.. Lugs R project from theoutside of the hood, and similar lugs, S, project from the outer side ofthe sleeve, and to the lugs S are secured rods T, .that pass througheyes formed in the lugs lt. The sleeve is provided witli a funnel-shapedmouth, 1?', corresponding in size to nearly the diameter of the boiler.The sleeve is moved back and forth on the hood by means of a lever, U,fulcrumed in the front side of the smoke-box, and a rod, V, connectingone end of the lever with the sleeve, and an actuating-rod, V, thatextends from the opposite end of the lever to the cab within easy reachof the engineer,who can thus cause the sleeve to close or enlarge theopening to the chimney, and thus regulate the draft.

The exhaust-steam from the pipes O forces the smoke, gases, so., whichenter the hood from the boiler-lines and the sleeve through the pipes Ninto the ashpit beneath the grate. The smoke, gases, dsc., mingled withthe eX- hauststeam are consumed by the re in the fire-box, creatingastrong draft and au intense heat,.and enable slack coal or screeningsor other cheap fuel to he used to make steam.

Among the advantages gained by my improved devices is that the two orthree upper rows of boiler-fines will not become choked with soot, as isthe case with the locomotives in common use, and, owing to thegreatly-increased draft, steam can be madein plenty with very littlelabor. Vhen going downgrade, and on other occasions when steam is notneeded to be supplied to the engines, the sleeve can be moved in againstthe head of the boiler, and thereby almost entirely cut off the draft,and thus effect a great economy in fuel. The sparks, cinders, andheavier products of conibustion will fall into the smokefunnel l, and beextinguished by the water resulting from condensation of a portion ofthe exhaust-steam. Vhen a sufficient quantity of extinguished sparks andcinders have accumulated in the IOO in the smoke-box and having themovable sleeve I), for regulating the draft, the exhaustpipes O,extending into the hood, and the pipes N, leading from the hood to theash-pit, for the purposes described, substantial] y as set forth.

3. The combination of the spark funnel or receiver I, located inthesmoke-boiz and having `the hood Hv and the tilting bottom or valve,

with the exhaust-pipes O, extending `into the f hood, and the pipes N,leading from the hood' to the `ash-pit,` substantially as described@I 4.The combination of the spark funnel or receiver I, located in thesmoke-box andhaving a bottom or valveadaptedlto dischargeits contents,and the hoodiH, withthe exhaust-` pipes O, extending into the hood, thepipes N,

leading from the hood to the ash-pitfthe sleeve l?, sliding on the hoodand having thelfunnelshaped mouth, and means for moving the sleevei toregulate the draft,substantial1y as described.`

In testimony that I claim the foregoing as my own I have hereto affixedniysignature in presence of two witnesses.
